BACKGROUND The tumor suppressor p53 protein plays a critical role in different cellular processes in response to DNA damage and it is responsible for transcriptional induction of the p21 (CDKN1A/WAF1/CIP1) gene. Both p53 and p21 are thought to play major roles in the development of human malignancy. Polymorphic variants of p53 at codon 72, and CDKN1A at codon 31, have been found to be associate...
PURPOSE The arginine to proline substitution at codon 72 represents a common aminoacidic polymorphism of the p53 protein. Recent data suggest that p53 codon 72 may modulate the response to cancer therapy. The aim of this study was to test the hypothesis that the p53 codon 72 genotype, evaluated in the tumor tissue and in the disease-free lymph node, is related to differences in disease-free and...
aim : the propose of this study was to evaluate the probable correlation between exon and intron polymorphisms of p53 gene and their association with clinicopathological aspects of gastritis. background : regarding to the decisive role of p53 in the development of a variety of human cancers, a comprehensive study concerning probable correlation between polymorphisms in the p53 intron and exon i...
BACKGROUND Codon 72 (Arg/Pro), the most frequently studied single nucleotide polymorphism (SNP) of p53 to date, is associated with the ability of the gene to induce cell apoptosis. The PI3K/Akt pathway plays an essential role in the transcriptional activation function of p53, and is an important factor in radiotherapy resistance. The present study was designed to evaluate the prediction of resp...
Background: The polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. From the evidence that the DNAmismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability; a feature of malignancies as...
